Jammin’ Jars Slot – Review & Free Play Casino Demo

Jammin’ Jars is a slot, but not as we know it. The gameplay and aesthetics of this very original title from Push Gaming owes a lot to the classic video game, Tetris.

The Jammin’ Jars slot is a massively colourful game with a busy screen and a lot going on both visually and in a game that is heavy on special features.

There’s a lot of crossover between the slots and video game world, and it’s something we’re only likely to see more of as slots companies try to get video games players – of whom there are many millions – to sign up at online casino sites and play their games.

Jammin Jars slot isn’t that recent, as it was released in September 2018, but it’s been a popular title for this company, once nearly hitting the top 20 of UK titles according to the industry audit site we use.

But should you pop open the lid of this fruity jar?

Let’s have a look!

Push Gaming – The Developers of Jammin’ Jars Slot

Push Gaming are not one of the giants of online video slots. They were founded in 2010, but still have only 32 titles on the market. That’s not bad going in just 120 or so months, but the giant companies push out a release a week!

It’s quality that counts though, and according to their own publicity that’s been the main focus of this company founded by two London chaps back in 2010.

The company is fully licensed in the UK, and also by the Alderney Gambling Control Commission, a regulator for the Channel Islands, a semi-off-shore jurisdiction that is popular with UK businesses because of its lower tax rates. Both are reputable regulators and show that you can trust this company.

The company is an award winner, and this title has won one of those prizes as a Best High Volatility Game.

The Jammin’ Jars slot is the company’s second most popular title, after Razor Shark, and above Wild Swarm, Fat Rabbit and Blaze of Ra. Just a glance at these titles show that Push Gaming take their design work very seriously – they all look amazing.

The Facts and Figures about Jammin’ Jars Casino Slot

This game has a theoretical return to player of 96.83%, which is quite high for the current market, and certainly respectable. This measure records how much of the money that is played in a game should be returned to players if they behave in a particular way. Another way of putting it is as a house edge of 3.27%.

The game’s volatility or variance is high. That means that it is likely – see the cautionary note about RTP above – to pay out bigger prizes but to pay out prizes less often. This measure is comparative, so you’d need to play other games to even understand it!

High volatility games generally have high top prizes. Here it is a potential 20,000-times your stake. Your stake can be 0.2 to 100 coins, which should be 20p to £100 on UK sites. Always be sure you check all the financial limits on sites you’re using.

The layout is an 8-by-8 grid. Betways aren’t counted in this game that awards prizes to clusters.

You can play this game on any device that supports JavaScript and HTML5.

The Game

Although the Jammin’ Jars slot game has a number of non-standard features, the set-up as far as the player is concerned is very familiar.

At the left is a menu grid to open up more information, to the right of it is a sound control, then your balance, then the bet, and a plus and minus option, then the information window, where your wins show up, with an autoplay option coming before the spin button.


This jar is full of fruits!

The game pays in clusters of between five fruits, with a top-level of groups of 25 or more fruits.

The fruits in order of increasing value are:

  • Blueberries, paying from 0.1 to 10 coins;
  • Plums (0.15 to 25);
  • Apples (the same);
  • Raspberries (0.25 to 37.50);
  • Oranges (0.5 to 62.5), and;
  • Strawberries (1 to 100).

There are also special symbols.

The jam jar is a wild that also acts as a multiplier, with a value that increases each time it appears in a winning combination.

Jammin’ Jars Slot Bonuses

There are a lot of bonuses here.

We have mentioned the wilds. Each wild win triggers a respin/cascade with the wild remaining in play until it falls off the bottom of the grid.

The rainbow feature activates at random after a losing spin. The rainbow floats over the grid leaving a super-sized fruit that brings in adjacent matching symbols for a win.

Free spins are triggered by the jam jar wild. Three wilds trigger six free spins, with the wilds remaining on the grid as sticky wilds. New wilds share this property. During free spins, the increasing multiplier does not reset after losses. Respins/cascades stay in play.

Our Expert Verdict

This is a fun, original game that looks and sounds fantastic and plays beautifully.

Anything that offers something a little bit different from the classic fruit set up is worth a bit of your time, and Jammin’ Jars slot takes the oldest tropes of the game – fruits – and really gives them a modern spin.

Gameplay has a lot of variety, with bonus features cropping up throughout the gaming cycle, and keeping your interest piqued at all time.

This is high volatility so you may have to wait for a win, but if you get the top prize here at the top stake (play safely at all times!) then you could win £2 million, which is a good prize by any measure.

Jammin’ Jars casino slot is one of the best and most original takes on the fruit genre we’ve ever seen and a genuinely great addition to a busy genre segment.
